TV-sets emiting "blue" light when looking into windows

hi there,

I always wondered why - when looking at night into windows where TV-sets are on you always see those rooms lighted in a blue hue, independent of the color of the color displayed on the screen (e.g. green for a football transmission)

what’s going on here?

thx

just wondering …

was my Q. unclear (no native speaker) … or didnt anybody come up with an answer (or an educated guess)

cheers

Padeye gave a good explanation in this thread. I think that’s what you’re looking for.
